Thanks for your answers guys, but i don't think we have solved the problem. I don't have the Google toolbar as a default, so I don't think that is causing the problem. The firewall/anti virus protection that I use is PC Guard supplied by Virgin Media. I have checked through this thorougly and cannot find any settings that affect the home page. Probably also related to the same problem is the fact that any web addresses that I type in are also lost from the drop down menu as well as the home page.
